[gentoo-user] Problem when going to install refind and using musl/llvm profile

[Andrew Lowe]

Hi all,
	I'm attempting to set up a new machine. I want to try out the musl/llvm 
combo, profile 70, but am having troubles with the refind boot manager.


When I attempt to emerge refind, I get, during the "pretend phase":


* ERROR: sys-boot/refind-0.14.0.2-r1::gentoo failed (pretend phase):
 *   objcopy (objcopy) does not support EFI target


and a bit further down:


* The specific snippet of code:
 *  LANG=C LC_ALL=C "${OBJCOPY}" --help | grep -q '\|| die "${OBJCOPY} (objcopy) does not support EFI target"



Has anyone gone down the road of musl/llvm/refind and seen this? I don't 
see anything under bugs.gentoo.org.


Any thoughts on how to fix this would be appreciated,

Andrew

[gentoo-user] New build, openrc, llvm, musl etc

[Andrew Lowe]

Dear all,
	It's been a while since I built a Gentoo machine from scratch so need a 
bit of guidance.


	I want to build a machine, amd64, that uses OpenRC, LLVM & Musl. 
Looking on the Downloads page and in turn the "Advanced choices", there 
is two separate Stage 3 archives, "llvm/OpenRC" & "Musl/OpenRC".


	I understand why I should have Musl as the default install. I'm 
assuming that I should just use the OpenRC/Musl Stage 3 and then just 
install LLVM as per normal, "emerge llvm" and things would end up being 
what I want - am I right? Or is there something special in the 
"llvm/OpenRC" archive that I also need to do?


Any thoughts are greatly appreciated.

Regards,
Andrew

I asked this on the KDE User list eight days ago, but no reply.



	The thingy between "Ctrl" and "Alt", looks like the "Win 98" logo? 
"Task Manager" - the thing that has all of the programmes, "log out", 
"Shut down" etc? If you use the mouse off the task bar it's called the 
"Application launcher"? Still there for me.


	Display the task bar via moving the mouse to the appropriate posi, I 
have the task bar across the top of the screen so I move the mouse to 
the top and then the left hand corner where the little 9 dot icon is. 
Select that and the launcher drops down. Next to the Search box is the 
little two slider looking icon, "Configure Application Launcher". Select 
that then "Keyboard Shortcuts". Select the key you want. Although I've 
just noticed, that even though I changed this, to now be be "F12", which 
works, the Windows icon still works.


	Or are you referring to the thing accessed via "Ctrl" + "Esc""? Don't

	Broken for me as well. I did a big update a few days ago and had 
noticed the same problem. I was about to  post the same as Dales 
original post when Dales popped up. I agree with Neil, about being near 
a file and clicking on the LHS.


	If I remember correctly, and I'm quite prepared to be corrected here, 
in the earlier versions the "highlight bar" only covered the file/dir 
name, not right across the whole window, Size, Modified, Type etc. Now 
it does, from the vertical line that indicates the dir tree right across 
to the RHS of the window. It does not extend right to the edge of the 
LHS of the window from the vertical line and that's the part that Neil 
identified. I'm guessing that dolphin somehow uses the highlight colour, 
the "highlight bar", to indicate location within the window and in turn 
as to whether things can be pasted there or not.


	If I didn't have, literally, three solid days of 1st year engineering 
students submissions to mark, I would have a quick squizz at the dolphin 
code, but it's out of the question at the moment. There is nothing on

[gentoo-user] Graphics problem, especially when running Firefox - kde environment

[Andrew Lowe]

Dear all,
	Back story, I'm in Perth Australia, hence summer has just finished. 
Summer here means long runs of about 40ºC during the day and nights of 
about 35ºC at midnight.


12 months ago, I started getting a dialogue popup that said:



KWin Window Manager
Desktop effects were restarted due to a graphics reset



This would pop up, particularly when doing "deep research" with Firefox 
on Youtube. Firefox would freeze for a few seconds, but the audio would 
continue, the screen would do a refresh/flash sort of thing and on goes 
the "research". As the day would progress, and the home office would 
heat up, 35ºC during the day, these popups would pop up more and more 
and the machine would nearly become unusable.


It was also accompanied by the following in dmesg:

This started last summer and then as things cooled down, occurred less 
and eventually disappeared, winter time. This summer it's back and even 
worse so I upgraded from an nVidia 1060 to a 3050 - the thinking being 
the card was over heating. As you guessed the problem is still here.

From the manpage:

   Most  errors  can be corrected by the CPU by internal error correction 
mechanisms. Uncorrected
   errors cause machine check exceptions which may kill processes or panic 
the machine.  A  small
   number  of  corrected errors is usually not a cause for worry, but a 
large number can indicate
   future failure.

   When an uncorrected machine check error happens that the kernel cannot 
recover  from  then  it
   will  usually  panic  the  system.   In  this case when there was a warm 
reset after the panic
   mcelog should pick up the machine check errors after reboot.  This is  
not  possible  after  a
   cold reset.

If you are overclocking, try disabling it.

You can try to re-encode or maybe remux with ffmpeg.

More than likely the metadata in the file is off.

This playback issue can happen with VBR MP3s and also Oggs as the length of
the file can be spoofed in the header.

Re: [gentoo-user] Windows 10 Pro 64bit in Virtualbox

[Andrew Udvare]

I use with a highly customised image made with NTLite where nearly
everything is removed, especially things like the antimalware, Cortana, etc.

This gives marginal gain in terms of boot up time, and general speed of the
UI (even with all animations disabled). It does however reduce the memory
requirement to about 1-1.5 GiB, which is nicer than average. However, that
barely fits a browser like Chrome or Edge.

I've been trying to perfect a minimal image setup for VirtualBox for a

Ha, the problem is back, dolphins everywhere. The problem seems to be, 
for me at least, that when I close Dolphin after doing a bit of 
file/folder stuff that the GUI shuts down but some zombie part remains. 
Just now, when I fired the machine up, I had three instances of Dolphin 
running. I closed all three, little red button top right hand corner and 
did a:


ps -A | grep dolphin | wc -l

Sure enough 3 zombies. Open Dolphin, do some "stuff", close Dolphin, do 
the "ps" command above and I' ve now got 4 zombies. Do this a couple of 
more times and I now have 8 - 9 zombies.


	Clean out ~/.config/session, ie it's now empty, and shut the machine 
down. Restart machine and hey presto, 8 - 9 Dolphins up and running and 
~/.config/session contains 8 - 9 Dolphin "restart config", or whatever 
they are called, files.


I think it is time to head over to some KDE forum and ask questions 
there.

To me it's suggestive of something messed up in a config file.

What does your .config/dolphinrc file look like?

At the level of KDE in general I have no idea what config file/files it
looks at when configuring the complete desktop environment but that would
be the next thing I'd go looking for.

I'm assuming (bad idea) that you've done a very simple experiment like
closing all the dolphin windows and immediately logging out of KDE?

Mark,
	Thanks for the suggestion. It wasn't actually dolphinrc but the 
~/.config/session dir that contained the problem. It appears that just 
during my normal day to day usage of the machine, I would open Dolphin, 
use it, then close it, rinse, repeat. The GUI would close down but some 
part of Dolphin would remain running. This resulted in, the time I 
finally spotted this, 28 instances of this "zombie" running.


	When the machine was shutdown at the end of the day, these 20 odd 
zombies would write a file into "session" for start up next time - which 
they in turn did the next time the machine started up, but this time as 
the full GUI + zombie.


Cleaning out session and killing all of the zombies fixed the problem.

Andrew

[gentoo-user] Multiple instances of Dolphin automagically appear upon login

[Andrew Lowe]

Hi all,
	A reworking of the subject line from my earlier post regarding pods of 
Dolphins...


	I've just started up and then logged into my up to date KDE machine. 
Once the machine is logged in and ready to go, I have, on the boot/login 
just now, 20 instances of Dolphin running. This is straight after login, 
I have done nothing to the machine after hitting "enter" when entering 
my login password.  This number also appears to be increasing each time 
I log in.

Hi all,
	My desktop machine is up to date ~amd64 along with KDE. A few days ago 
I think I had, amongst others,  a Dolphin update. Now when I turn on the 
machine and log into KDE, I find that I have, for example the login I

running. I have not tried to "customise" Dolphin or set anything to 
autostart in the last couple of days.

some Googling and will do some more but I can't find anything.

The thought process is the same as the guide you are reading. 
https://www.oreilly.com/library/view/kerberos-the-definitive/0596004036/ch04s03.html

It says in the last paragraph on this page that the /etc/hosts file should have 
the '127.0.0.1 localhost ' (last part is definitely optional) and 
then that the next entry should have the outer IP address mapped to the FQDN.

No because how it's done is totally dependent on your needs. There's no one

kinds of file systems or other things that cannot be covered. Gentoo is all

Re: [gentoo-user] Nodejs overlay

[Andrew Udvare]

 Node-based (or Yarn-based) project. I 
also don't consider it too much of a burden to add ~/.node/bin to PATH.

I am on a single user PC, but those with a server shared between users may want 
to have a truly global Node setup without using npm -g alongside Portage. This 
hypothetical user base is probably way too small to support right now. The 
convenience is high (one package manager to rule them all) but the cost is much 
higher.

One could argue for something like 'create-react-app' having an ebuild, but if 
all its dependencies also had ebuilds, it would be the one of the largest dep 
trees if not the largest, just for one package. Nightmarish to maintain because 
the next update will probably update a significant number of those deps too. 
Things like ESLint and Webpack would be a nightmare too, especially once their 
plugins get involved. Again the question here is whether Portage would even 
scale well with this many packages brought in from Node, treated the way we 
treat Python packages or Perl modules.

Java is in a similar boat to something like Node. Anything that we want written 
in Java on Gentoo generally just gets added as a -bin ebuild. Even if this 
wasn't the case, it would be easier to maintain all-in-one ebuilds that grab 
all deps and build with Maven (which too is a bin only in Portage) as opposed 
to the separate deps.

It can't be done in a sane way. Nodejs, because of their unwillingness to solve 
dependency issues and allowing insane amounts of tiny packages to exist (blame 
the community), allow insane dependency trees that make it impossible to put it 
on top of a normal package manager.

Even if we did find packages that don't have these conflicts, having Portage 
manage thousands of packages just for a single thing like eslint seems like a 
very bad idea.

Our best option is to treat Nodejs stuff the way we treat Rust and Go packages. 
Pretend Nodejs 'binaries' are 'built' statically and therefore, grab all the 
dependencies in the main package ebuild. One example is this overlay's vscode 
ebuild: 
https://data.gpo.zugaina.org/pf4public/app-editors/vscode/vscode-1.52.1.ebuild

The process of generating the SRC_URI can be automated. Eclasses could be 
written for to help with the phases, especially src_unpack and src_prepare.

KDE Connect works over wi-fi by having your phone and computer on the same
network. You must run the app on your phone and it should see your computer
if it is running KDE Connect.

Make sure you allow the KDE Connect ports in your firewall. 1714-1764 for

Unless I'm mistaken, this is happening because of the -N flag to

USE flags, it wants to rebuild them.

I usually stick with -U (--changed-use) instead, when emerging world.
  This only rebuilds packages when the flags *change*.  Give that a go.

to do update the Gentoo install whilst winding down. I've done an:


eix-sync

followed by an

emerge --ask -NuD world

and am now confronted with a huge list of thingies that need rebuilding. 
For example,


[ebuild   R] media-video/ffmpeg-4.3.1  ABI_RISCV="-ilp32% -ilp32d%"

is amongst the 249 items that want to rebuild. I do have some valid 
updates on top of these but 249 rebuilds that appear to be triggered by 
ABI_RISCV.


Is there a simple way of stopping this? Can I just place something such 
as:

ABI_RISCV=""

in the make.conf file and that will tell portage that even though I 
think the idea of RISCV is interesting, and all power to them, I don't 
need it on an AMD 64 bit machine hence don't rebuild all my stuff.


Any guidance anyone can provide would be greatly appreciated.

Probably the kernel is blocking write access to EFI. This is on purpose
for safety as you can damage your firmware quite easily. systemd-boot
and others do not have this restriction. You also should be careful
writing to the EFI too much as the NVRAM flash may not be of high quality.

https://lwn.net/Articles/674940/

You can try using `chattr -i` against the files like:

chattr -i /sys/firmware/efi/efivars/Boot*

Then you can try with bootctl and others, but this is not guaranteed to
work.

On my ASUS motherboard I haven't been able to write to EFI variables
from within Linux for a long time. I have to add my keys in the BIOS and
set the default in systemd-boot.

The logic to write to a file in efivars is here:

https://github.com/torvalds/linux/blob/master/fs/efivarfs/file.c#L15

If you use strace with bootctl you'll probably see one of these errno
values.

For Qt apps you might want these environment variables in .xinitrc:

QT_SCREEN_SCALE_FACTORS=DVI-I-0=1.5;DVI-I-1=1.5;HDMI-0=1.5;DP-0=1.5;DP-1=1.5;DP-2=1.5;DP-3=1.5;DP-4=1.5;DP-5=1.5;

(These device names are the same as what xrandr shows.)

QT_AUTO_SCREEN_SCALE_FACTOR=0

Currently I have an issue where opening Qt apps from certain contexts results 
in resetting the DPI scale to 2 instead of 1.5. Primarily this happens when 
Chrome launches a Qt-based viewer such as Kate, and sometimes it happens from 
Konsole. Have yet to file bugs.

Do you have an ~/.Xresources file? It can have something like:

Xft.dpi: 144

Which is also passed to Xorg for me: -dpi 144 (Plasma does this by

[gentoo-user] Anyone willing to share a kernel .config file?

[Andrew Lowe]

Hi all,
	I have an AMD Ryzen 7 2700 CPU sitting in a Gigabyte X470 Aurus Ultra 
Gaming motherboard with 64GB of RAM and an nVidia graphics card. For 
some reason I've never been happy with the kernels config. Considering 
the grunt this thing should have, I am seeing nothing like what I would 
expect. By way of example, if I am running a vid through VLC on one 
screen and get Firefox to create a new tab within the browser on another 
screen, the video in VLC freezes for several seconds. Other things 
freeze when I think they shouldn't be.


	I know this problem could be related to Qt, KDE, VLC, Firefox etc, but 
I think I will take this opportunity to check that my foundations, the 
kernel, are solid in the first place before I start looking at other stuff.


	Does anyone have a physical configuration like mine, and that they 
think runs well, and are willing to share the .config file?


Regards,
    Andrew

Since you are using systemd-boot or something that fulfils that
specification[1], you can also build your kernel with EFI stub enabled
(CONFIG_EFI_STUB) and then simply put the binary in:

${ESP}/EFI/Linux/vmlinuz-5.7.1-gentoo.efi

You can then run `bootctl set-default vmlinuz-5.7.1-gentoo.efi` or on
the menu, select it and press d to set it within systemd-boot.

(My ASUS motherboard for some reason never lets me write EFI variables
from within Linux so I have to do it from within systemd-boot.)

You can specify the options in the kernel configuration as well:

CONFIG_CMDLINE="root=/dev/nvme0n1p4 initrd=/intel-uc.img net.ifnames=0
raid=noautodetect"

To add the /intel-uc.img to this configuration you either have to
include that in kernel configuration or you can use Dracut to build an
EFI image.

Kernel config:

CONFIG_INITRAMFS_SOURCE="/boot/intel_uc.img"

Or with Dracut:

dracut --force --uefi --uefi-stub
'/usr/lib/systemd/boot/efi/linuxx64.efi.stub' ...

Dracut will automatically pick up your kernel installed to /boot (from
kernel `make install`) and /boot/intel-uc.img (and other similar
things). It will also automatically place the file into

In both cases, you have to remember to update the EFI image/rebuild and
reinstall the kernel whenever you update intel-microcode.

The benefit to this is you don't have to maintain entries files, and you
keep configuration generally in one place: the kernel config. Then you
just drop in EFI binaries into the correct place and they will appear in
the menu. You could have always keep two Linux EFI binaries in
${ESP}/EFI/Linux/ in case the newest one fails.

If you want to do this semi-automatically as part of updates and with
UEFI secure boot signing, use my project: https://github.com/tatsh/upkeep

Sounds like missing drivers. oldconfig didn't do everything it was
supposed to. Moving across multiple major versions, this is to be
expected. A lot of names of things have changed.

Do a comparison of your configuration between old and new.

diff -uN old-config-file /usr/src/linux/.config

Make sure to at least enable NVME with CONFIG_BLK_DEV_NVME=y and try
booting 5.7 again. Other than that, the naming scheme may have changed
but I don't know about this. For better future-proofing, use a UUID of
your root partition rather than a device name.

root=UUID=...

You can get this UUID with the blkid command.

I would keep GCC 9 for now. I've run into a few issues with GCC 10
compiling various packages so I have kept GCC 9 on my system. There's

[gentoo-user] Updated world -> KDE colours have gone feral....

[Andrew Lowe]

Hi all,
	A few days ago I did an "emerge -NuD world" on my KDE based desktop 
machine. When I rebooted the machine, the colours had gone a bit weird. 
I use the Nordic scheme which is dark but now, for example, when I open 
Dolphin, the alternating horizontal stips/stripes that go from the 
dir/file name across through the Modified/Type/Size area have undergone 
a colour change with the lighter horizontal stripes now nearly the 
colour of the text hence I can't read every second row. Other 
applications also display this behaviour, it appears that the colour 
palette is being modified somehow!


	If I go into the "System Settings" and change the "Global Theme" to 
something else, say "Breeze Dark", apply, then change back to Nordic, 
hey presto the colours are back as they should be. Reboot and the dodgy 
colours are back, go to "System Settings".rinse, repeat..


	Anyone have experience with this sort of problem? Is there a way to 
reset the palette? Is there a way to refresh/reset the theme? I don't 
have a whole series of customised keystrokes etc so if it's a case of 
just blowing away a config file/dir and then the system will reset 
itself, that's not a problem.


Any thoughts are greatly appreciated,

You're referring to Blu-ray authoring like creating menus and making a
video disc that works in a set-top player. There isn't any software for
Linux I know of that does this, especially the menu part. The menu part can
be in a simple format or it can be more advanced with BD-J.

nftables.

You definitely do not need zfs installed to use Docker. This machine
doesn't have it.

As Victor stated, CFQ is deprecated and gone and BFQ will work fine. And
the script is basically for Red Hat (or corporate) users who still use
iptables, CFQ, ext3 apparently, and a much older kernel.

On my slightly stabler server (running 5.4.38), this is the output and
Docker still works fine. Again on that server I use nftables and manage
the firewall manually. The system has ext4 for its root and the rest of
it is ZFS.

Because not every user has UEFI and many just use the BIOS compatibility layer 
(CSM) if they don't care about UEFI and Secure Boot. The CSM is going to be 
there for a very long time.

If you don't need UEFI features, then there's nothing really wrong with using 
CSM. I am using UEFI because I like having a signed kernel and signed boot 
loader (systemd-boot).

I can tell you there's a huge difference in speed as NVMe is essentially the

You shouldn't have a problem with either. I've been booting with my own signed

If for some reason the motherboard won't take your self-made certificates/etc,

[gentoo-user] The saga of the missing Logitech drivers

[Andrew Lowe]

Hi all,
	I posted something a few days ago about middle click of a mouse not 
working. In investigating this, I think I have come across something a 
bit dodgy.


	I have just updated my kernel to 5.5.0. This has the dodgy behaviour of 
the middle button not working.   A bit of Googling led me to reboot my 
machine with an older kernel, 5.4.14. The middle button worked. The 
kernel is the problem I thought. I in turn diff'd the configs for the 
two kernels. 5.4.14 has 7 lines of Logitech stuff under CONFIG_HID_. 
5.5.0 has none. The Logitech stuff appears in the 5.5.0 kernel if I 
search within the kernel config thingy, "make menuconfig". It should be 
noted that I usually roll my old config file over into the new kernel 
then run "make oldconfig".


	"make menuconfig" under 5.5.0 shows, in my situation, Device 
Drivers->HID support->Special HID drivers:


...
...
Kensington...
LC-Power
Lenovo...
Apple Magic...
Maltron...
...
...

Under 5.4.14 there would have been a Logitech between Lenovo & Magic Mouse

	With this in mind, I deleted the current config file, the one based on 
5.4.14 with "make oldconfig" and missing Logitech and then reran "make 
menuconfig". Working my way down to the mouse drivers, lo & behold, 
there are entries for the Logitech mice. When I exit "make menuconfig" 
and look at the .config file, the Logitech stuff is there.


Now the big questions are:

1) Is "make oldconfig" broken?
2) Can I no longer take my old config across and update it?
3) Am I a dill and doing something obviously wrong?

	I don't want to have to start from a fresh config file and weed out all 
the %^&^$^#^# stuff I don't need, all of the weird network cards, the 
Intel CPU stuf, I run AMD, etc etc.


Any thoughts on how to rectify this situation would be greatly

[gentoo-user] Dolphin problems...

[Andrew Lowe]

Hi all,
	I'm running an up to date KDE machine. In the last couple of weeks when 
I fire up Dolphin to browse the file system I get some weird behaviour.


	When the app first displays, I have "Places" on the LHS, the file 
system in the tree on the RHS and a shell across the bottom, in other 
words, nothing customised, basically "straight out of the box". The 
weird behaviour is that when the app first displays, if I click on any 
of the "Places" nothing happens. Normally there is a light "highlight", 
I'm using a theme that is dark in colour, that follows the mouse over 
the "Places" and a click on a "Place" will jump the tree view, and 
shell, to that part of the file system. Currently that does not happen. 
If I use the cursor keys I get movement in the tree view. I also just 
noticed that if I click in the shell it does not get focus as well.


	The interesting thing is that if I shrink/minimise the main window of 
Dolphin, it is back working as expected, the "highlight" follows the 
"Places" as I move the mouse over them, the shell can get focus if I 
click in it. Maximisings the window still has it working as expected. 
It's as though when the app first starts up, things are not getting 
mouse focus info and the shrinking/maximising then sets the focus correctly.


	Has anyone seen this behaviour before? As I said at the start this is a 
recent "feature" previously things were working as expected.


Any thoughts?

Get to a point where you know for sure nothing is writing to the disk (or would 
be) and make an image with dd, then leave the physical disk alone. Then start 
recovery.

I attempted to do this migration on two machines but was only successful
once. Pretty sure this is because of not using 17.1 profile on the
failing machine.

The first machine is on a 17.1 profile, and migration was relatively
simple, and worked. I did it based on this post:

https://forums.gentoo.org/viewtopic-p-8373904.html?sid=5c30f451df89c01a6bbe0a8dadd77c36#8373904

On the second machine, I did not change to profile 17.1. After moving
the files around, no matter what I tried, Portage refused to check the
new DISTDIR. I haven't had time to switch this machine to 17.1 yet.

It's probably complaining if you're running as root and you've set the GPG home 
did to be in /home/purslow/.gnupg rather than /root/.gnupg (and owned by 
root:root). Otherwise try setting that directory to 0700 permission (u+rwx

For anyone interested, here are some pictures of the panics:

https://i.imgsafe.org/5e/5e20756985.jpeg (unknown)
https://i.imgsafe.org/5e/5e20754111.jpeg (find_css_set)

The driver in question is the one named ProCapture. I am fairly certain
this is the cause of the recent panics.

I have had some issues with overclocking my system (both CPU and memory)
but I do not think this is related. Just for good measure I reseated all
my RAM modules. I am currently running 3.7 GHz (from 3.5) with memory
overclocked to 2667 MHz. Does not seem to have an issue.

Thanks for the reply.

I think I have found the issue in another 3rd party blob-ish driver from
Magewell, which is for my capture card. I removed the capture card
(since this would stop the module from loading) and my system has not
had a panic since. I have not tried to upgrade back to 5.4.2 yet but as

[gentoo-user] Kernel panic on 5.4.2 - not sure of cause yet

[Andrew Udvare]

I have been getting relatively consistent kernel panics on some call to
find_css_set and sometimes a stack trace that mentions cgroups.

On 5.4.0 I don't get this same crash and I added blocking of
auto-loading nvidia under the ramdisk just in case that's the issue, as
I was sometimes getting a similar crash on 5.4.0.

/etc/default/grub:

GRUB_PRELOAD_MODULES=lvm
GRUB_CMDLINE_LINUX="init=/usr/lib/systemd/systemd
systemd.legacy_systemd_cgroup_controller=yes rd.driver.blacklist=nvidia
rd.driver.blacklist=nvidia_modeset rd.driver.blacklist=nvidia_drm"
GRUB_GFXPAYLOAD_LINUX="keep"

The reason the legacy argument is there is because Docker won't work
under the new cgroups, for now.

I have a couple of modules, but the one that sticks out most is nvidia.
This is the one I see in the stack trace. I have not seen a bug report
on Gentoo or Nvidia's end.

For now I've masked >5.4.0 gentoo-sources.

Anyone else getting a similar issue?

Thanks

For Python (any version), use wheels:

https://pypi.org/project/wheel/

You would have to clone/download the packages yourself, and then run `python 
setup.py bdist_wheel` for them. This also ensures that you preserve compiled 
versions of the packages. As time goes on, these older packages will not 
compile against newer GCC/Clang versions without patches. Most popular packages 
already have wheels, although they might not have every combination built.

For anything else, if it doesn't need stuff like hardware 3D acceleration, use 
a VM that retains the packages you want. This also leads into...

If it does need native hardware access, use chroot and/or disk images (that you 
would boot into separately). I prefer to try and create barriers between 
'production' (what I use everyday) and one-off things like some old game that 
only supports 32-bit.

You probably want to retain old versions of toolchains (GCC, binutils, Clang, 
LLVM, etc) in case you need to build anything (built with -mtune not -march). 
Use Gentoo's binpkg format for this with the `qpkg` command. These packages can 
also be deployed on non-Gentoo systems but YMMV as you look for dependencies.

I tend to keep old hardware around for running old software. You might want to 
do the same.

A lot of older (much older) x86 support is being added to MAME everyday. This 
may come in handy in the future to preserve older versions of Linux distros and 
apps/games.

If you re-emerged atk successfully, then the gtk linking stage should
not fail with the same error as /usr/lib/libatk-1.0.so should now be in
the correct format (32-bit instead of 64-bit).

You have to pull in some packages in a very specific order.

With KDE we have a sort of circular dependency on freetype[harfbuzz],
because harfbuzz itself depends on freetype. For this reason I had to do
the following:

env USE=-harfbuzz emerge -1 freetype
emerge -1 harfbuzz
emerge -1 freetype

There is currently no way for Portage to do this automatically.

Your issue sounds similar and I would suggest emerging offending
packages separately before continuing the rebuild process for /lib32,
etc. The order is going to depend on other packages you have installed.

As soon as one of these special packages errors, you need to check the
build log. Most likely it was during the configure stage where a
dependency is not being found in /lib because it has not been built yet.
Build that dependency with --oneshot and try again with the failing
package after.

[gentoo-user] Docker + systemd since cgroups v2

[Andrew Udvare]

For reference: uname -r: 5.2.13-gentoo, systemd version 
243_rc2-r1[cgroup-hybrid], ACCEPT_KEYWORDS="~amd64"

My system started failing to start running docker.service automatically and the 
logs weren't too helpful. Finally I ran dockerd on its own and found that it 
gave me this error message:

Devices cgroup isn't mounted

This is not too easy to diagnose as there seem to be a set of solutions but 
none of the main two worked for me. One involved setting 2 options on the 
kernel command line:

cgroup_enable=memory swapaccount=1

And the other was to add USE="cgroup-hybrid" to systemd. I did this, but it too 
it did not work.

The other solution is to simply mount the cgroup manually and this works but I 
did not see why I'd have to do that now when I never had to in the past.

I actually had to add this to my command line:

systemd.legacy_systemd_cgroup_controller=yes

This has been noted in other distros but from what I can tell this is solely 
because runc has not been updated to be able to use cgroups v2.

Anyone else ran into this issue? Is there something I am missing so I wouldn't 
need to pass a kernel command line option?

Or grep with brackets:

ps aux | grep '[f]irefox'

I have a function for this:

psgrep() {
  ps aux | grep "[${1:0:1}]${1:1}";
}

This works because the ps output will have "grep [f]irefox" and the regex can't

[gentoo-user] Music player being run from an emerge

[Andrew Lowe]

Hi all,
	This all happens on an up to date openrc machine with the profile 
default/linux/amd64/17.0/desktop/plasma


	I've added a few hooks to the emerge process via the bashrc that is in 
/etc/portage. One of the things I do upon emerge failure is kill vlc, 
which would have been playing a random song, and then attempt to start 
alsaplayer[1] with a specific song. This means that I can be pottering 
around the house/shed and if the "failure song" starts playing, I know 
something is up. The problem is getting the failure song to play.


	If I log in as my usual user, alsaplayer will run the song. If I then 
"su" into root, I'm in wheel, alsaplayer will play the song. The problem 
is that when the emerge runs, then fails, alsaplayer can't appear to 
fire up. When an emerge fails, I get the usual error listings then the 
following:


 * ACCESS DENIED:  open_wr:  /dev/snd/controlC0
 * ACCESS DENIED:  open_wr:  /dev/snd/controlC0

.

Amongst this stuff is a line:

LOG FILE: "/var/log/sandbox/sandbox-20431.log"

which I think confirms my suspicions that something is wrong with my 
sandbox as I also get this error when the email fails and just before 
the failure hook, running alsaplayer, is run:


ERROR: ld.so: object 'libsandbox.so' from LD_PRELOAD cannot be preloaded 
(cannot open shared object file): ignored.


	Are there any emerge/sandbox gurus out there who might have an idea as

Not the same thing.

kfilemetadata is solely a library and should be pulled in by other

You have to enable USE="semantic-desktop" to make Dolphin and others
pull it in and use it.


If a GUI is not necessary and a semantic database indexing is not required,
you can give exiftool a spin, which can be scripted with find to search your
files and store them according to any exif tag.



	I spent much time getting rid of the semantic desktop so that's that 
last thing I need. I've given exiftools a go before and it gave me all I 
needed so a combo of the right click and it will give me all I need.

Thanks. Installing linux-firmware and adding this file to my initrd in

[gentoo-user] Where to put Happauge capture card firmware?

[Andrew Udvare]

I get this error in my boot log:

Jun 16 03:54:55 limelight kernel: cx25840 2-0044: Direct firmware load
for v4l-cx23885-avcore-01.fw failed with error -2
Jun 16 03:54:55 limelight kernel: cx25840 2-0044: unable to open
firmware v4l-cx23885-avcore-01.fw

I can get this file, but I have not figured out where I am supposed to
put it.

Thanks

https://github.com/torvalds/linux/commit/09324d32d2a0843e66652a087da6f77924358e62#diff-a3fadbb3daba4dd336ddc1846df3e6c8

Can also look at kernel.org.

I just dealt with this with the TRIM error and its patch.

The easiest way is to look at the patch file(s) being changed, and then go to a 
web mirror to check that file's history.

Example:
https://www.redhat.com/archives/dm-devel/2019-May/msg00104.html
https://github.com/torvalds/linux/commits/master/drivers/md/dm.c
https://github.com/torvalds/linux/commit/51b86f9a8d1c4bb4e3862ee4b4c5f46072f7520d#diff-309bcac7077137714d954d0a75c854d1

If you go to the diff for 5.1.4-5.1.5 (GitHub does not have these tags) you can 
see this patch was included in the release:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/?id=v5.1.5&id2=v5.1.4&context=3&ignorews=0&dt=0

It is possible to use kernel live patching, see [1] for details.
Most kernel bugfixes are available that way. I have not checked MDS
problem however.

migrate to statfs() or fstatfs(), that's easy.

It depends on the details of the problem, but you provided no
details to make further considerations. In general it would be
considered a bug.

It's better to fix your application. Fixing problem revealed by gcc
update is usually not hard.

It provides extra isolation features. If you are sure you don't need
that, ignore it.

This has been a 'feature' for a while. I find it very annoying.

I suppose the idea is to not have users get annoyed that their network card 
can't be used after building a (generic) kernel. And they consider it justified 
since network connectivity is crucial to get things done. More for the Ubuntu 
users than everyone else.

These days one can configure kernel to load only signed modules
(with public key compiled into kernel) and refuse to load all
unsigned modules [CONFIG_MODULE_SIG_FORCE]. During normal kernel
build process all legitimate modules will be signed
[CONFIG_MODULE_SIG_ALL]. All out-of-tree modules may be signed
manually as well [scripts/sign-file]. Afterwards signing key
[certs/signing_key.pem] may be removed from the system (e.g.
encrypted or deleted).

The benefit of this approach compared to kernel without modules is:
1) out of the tree kernel modules can be used (e.g. I use openafs)
2) kernel can be made smaller and faster by removing rarely needed
functionality into modules (e.g. support for various USB devices,
network protocols or filters and other subsystems which are not used
on daily basis, but may be needed occasionally).
